Don’t you just hate it when you go to the airport and check in your luggage, keeping your fingers crossed that a nice, broad smile with a wink will help you squeeze past the additional kilos onto the conveyor belt without forking out insane amounts of money that airlines charge? Well, you can easily avoid such a potentially embarassing situation if the attendant turns down your request (suggested via body language or otherwise), making you look like a miser who can afford to buy a plane ticket but can’t fork out the extra dough just to get that huge suitcase across the Atlantic. Well, best be prepared from home we say, with the Balanzza Mini Digital Luggage Scale more than ready to help. This £19.99 device lets you know how much your luggage weighs – all you need to do is attach your bag to the strap, pick it up by the scales and get a reading through its display. Switchable between lbs and kgs, it helps you bring only what is necessary, so that you can use the saved money on your vacation. Be warned that it has a maximum weight reading of 44kg or 111lbs.
